 * I tried clearing cache and server cache, but nothing is there. I had about 56
   blocks. Have been using it for several years, currently running version 11.4

 * Hello there,
 * Can you please try the Chrome browser and again make sure that it is 100% cleared
   of any cache.
 * Do you have phpMyAdmin? CJT will never just delete your code blocks as they are
   stored in the database.
 * It will only delete your code blocks if you checked the ‘Wipe out Data’ in Settings(
   cog icon), then Deactivated and Deleted the Plugin. But if you did not do that,
   then your codes should be safe.
 * Also try these general troubleshooting ideas below:
 * – make sure you are running PHP version 7.1 or higher
    – increase your PHP Memory
   limit to 128MB or even 256MB: [https://www.wpbeginner.com/wp-tutorials/fix-wordpress-memory-exhausted-error-increase-php-memory](https://www.wpbeginner.com/wp-tutorials/fix-wordpress-memory-exhausted-error-increase-php-memory)–
   make sure you don’t have any security plugins getting in the way – e.g. preventing
   AJAX from working in the Admin dashboard. – deactivating plugins one by one –
   deactivate your theme
 * Lastly and this is a long shot, according to this support post here, it could
   be one of two things:
 * 1) The file ‘jquery.block.js’ could be missing in the plugin during the plugin
   update. Added/modified necessary files in the plugin folder. You may need to 
   download the plugin manually and add that file in.
 * 2) There may be a JS file that seems to be looking for a CSS selector which is
   apparently missing. The selector class is ‘postbox-header’. Removing that CSS
   class reference from the JS file may fix the issue. This could be something to
   do with an older version of WordPress or some other plugin that might be removing
   that class from the admin area.
 * If you can post any errors from the CJT dashboard page via the console, that 
   may help.
 * Thanks

 * So I’ve tried everything above, but the code blocks I was using are still missing,
   but apparently running as see on this page.

 * I used it on many pages to send only a teachers posts to their page and to post
   menus in pages.
 * The CJT Console is blank as in no templates or previous code showing.
    Here is
   what’s running
 *     ```
       PHP
